Hemogram is a schematic account of the results of quantitative and qualitative researches of blood. In the hemogram note the number of red blood cells in 1 mm3 blood, change their size, shape and color; the number of reticulocytes in percent to the total number of red blood cells, the number of hemoglobin and a color indicator, the number of cells in 1 mm3 blood and percentage of individual types (WBC), pathological changes in them, the presence of pathological types, the number of platelets and peculiarities of their structure.
The blood is the result of interaction processes of blood and kirovogradschine. Hemogram gives an opportunity to reveal their balance or the predominance of regenerative or degenerative phenomena in the blood system. So, for example, leucocytosis with a shift to the left (with the increase mainly stab and young neutrophils) indicates enhanced regeneration, which is in most cases a defensive reaction to the established infection. Leukopenia with the decrease in the number of neutrophils and eosinophils occurs when oppression leikopoaiza. At an anaemia anisoles of erythrocytes, their polychromasia, the increase in the number of reticulocytes show the intensification of regeneration of red blood; poikilocytosis, basophilic grain size of red blood cells, rings Kabota - about the prevalence of degenerative phenomena in them. Changes hemogramme may be characteristic of certain processes. So, for example, eosinophilia characteristic of all allergic processes. At the same time, the emergence of eosinophils in the blood after its absence in infectious disease indicates the beginning of recovery. This is an example of what the hemogram cannot be considered in isolation from the entire clinical picture of the disease. Cm. also WBC, Blood.
